Abstract: A music library system that is adapted for the storage of sheet music, is designed for semi-permanent installation in a room having adjoining walls and a floor and includes a frame that is fixedly, removably coupled to the floor and to at least one wall of the room. The frame defines a plurality of drawer openings. A plurality of drawers are movably supported on the floor. Each of the plurality of drawers is disposed in a retracted disposition in close proximity to at least one other drawer in a corresponding drawer opening. The drawers are extendable from the frame outwardly from the wall to an extended disposition wherein a drawer side opening is exposed. The drawer side opening provides access to the stored sheet music.

Abstract: In accordance with the present disclosure, a portable riser unit for supporting persons or objects above the ground, a floor, a stage or the like is provided. The riser broadly comprises a base, generally rectangular step members, and hinge joints for pivotally, hingedly connecting the step members to the base. The base has an integrally formed, convoluted internal or interior support and baffle wall structure and may be filled with an appropriate low density, high volume material. Each step member also may be of this construction; however, the step members may or may not have an internal support wall. The step members are operably coupled to the base by double axis hinges including hinge blocks received in complementary hinge wells in the base and step members. The hinges are self-leveling to present a substantially smooth, level riser support surface in every possible configuration.

Abstract: An elevated floor has two separate types of floor panels arranged in alternating order on adjustable support legs. Base floor panels and access floor panels are formed from squares of low density oriented strand material having extruded metal cladding strips along the peripheral edges of the squares. The base floor panels include edge cladding strips having a support flange extending outwardly from the base panel peripheral edge. The access panels include a different type of cladding strip designed to seat on the support flange of the base panel cladding strip. Detachable riser beams are provided for assembly of multilevel stepped raised floors.

Abstract: A machine (10) for forming material into cylindrical bales of density increasing from the center to the periphery, comprising a mobile structure (11) including first (14) and second (15) body portions pivotably secured together on a generally horizontal transverse axis, a baling chamber (20), in the structure, defined by portions of the peripheries of a plurality of closely spaced conveyors in the form right circular cylinders (21-39) mounted with their axes parallel and passing through points lying on a smooth closed curve in a vertical plane perpendicular to the axis, the lower half of the curve being generally a circular arc and the upper half departing outwardly from circularity by an amount which varies smoothly to and from a maximum in the vertical direction: a pickup mechanism (80-83) is provided for gathering material to be baled from the ground and introducing it as a ribbon peripherally into the chamber at its bottom, and a drive arrangement (17, 60-67, 70-73, 84, 85) is provided for causing operati

Abstract: A plurality of fluffer shields mounted in generally end-to-end relationship on the frame of a crop harvester and conditioner. Each fluffer shield is pivotally adjustable independently of the other shields to control the rearward movement of portions of the cut crop delivered rearwardly of the harvesting machine by the crop conditioner rolls of the machine, so as to control the cross-sectional shape and density of a windrow produced by the machine.
